asp.net crosspage postback on click doesn't run -

I am trying to get a cross-pop postback to work in asp.net 2.0. I use press other Based on the values ​​of events, some session variables have been used to store click events. The CrossShot Postback property is on the relevant page in this button.

Click the event is not running at all, it seems that it directly postbacks to the second page.

Is this a standard practice?

I think I have found my answer

It seems that the transfer will happen immediately, no onClick event will run. Use alternative server. Transfer to OnClick Event

Any other comment appreciated.
